OIL-CUP.

Specification of Letters Patent.

Patented May 28,1912.

Application filed August 15, 1911. Serial No. 644,181.

I '0 all whom it may concern:

Be it known that we, WILLIAM H. Bans- SEL and ROBERT OI-IARA, citizensof the United States, residing at Pocatello, in the county of Bannockand State of Idaho, have invented certain new and useful Improvements inOil-Cups, of whichthe following is a specification.

This invention relates to improvements in oil cups, and has particularreference to oil cups, which are used on moving parts of machinery.

The principal object of the invention is to provide a simple andefficient means for retaining the feed plug or screw within the cup, andprevent the loss of same due to jarring of the machinery. These andother objects will appear as the description proceeds.

In the drawings: Figure 1 represents a portion of a connecting rodshowing our cup applied tion through the oil cup. Fig. 3 is a horizontalsection on the line 3-3 of Fig. 1.

Referring to the accompanying drawings, 10 represents the oil cup whichis provided with a threaded nipple 11 for engagement in the usualthreaded opening of the portion of the machine to be lubricated, anopening 12 leading from the interior of the cup through said nipple. Ascrew threaded plug 13 is adapted to be secured into the cup to forcethe lubricant through the opening 12, at the upper edge of the cup isformed a series of ratchet teeth 14, and below said teeth an annulargroove 15. A spring steel ring 16 which is open at one side and has itsends flared slightly outward as at 17 so that said ring may be easilyspread is disposed over the space in which are formed the ratchet teeth.The ring is formed with an angular bead 18 near its lower edge, whichwhen the ring is in posit-ion, will engage in the groove 15 of the cup,and prevent disengagement thereof. The plug 13 has cut longitudinalltherein a groove 19, which is adapted to receive the inwardly andupwardly directed lug 20 on the upper edge of the ring 16, at a pointdiametrically oppothereto. Fig. 2 is a vertical sec-' site to theopening thereof. One of the ends 17 is slightly thickened, and formedwith an angular shoulder 21 for engagement with the ratchet teeth on thecup.

Assuming the parts assembled as represented in Fig. 1, when desired toforce the screw plug into the cup to apply pressure to the oil said plugis turned by any suitable tool as a wrench which can beengaged with theangular portion 22 formed upon the upper end thereof. Rotative movementof the plug causes the advancing movement into the cup, and as the lug20 is engaged in the groove 19, the ring 16 will be carried aroundtherewith, the shoulder 21 engaging successively with the ratchet teeth14 and preventing a retrograde movement of the plug.

The. bead 18 engaging in the groove 15 in sures that the ring will notbecome displaced or detached from the cup.

It will be observed that the groove 19 terminates at a point a suitabledistance from the lower end of the plug, thus making it impossible forthe plug to be jarred out of the cup when in its uppermost position, forthe reason that the lug 20 will engage against the bot-tom of thegroove, and hold the same from both rotative and vertical movement.

What is claimed is:

1. An oil cup including a screw plug for engagement therein, said plughaving a longitudinal groove extending to within a distance of the innerend thereof, a resilient member 'on the cup, means on the resilientmember for engagement in the groove, means on the resilient member forengagement with means on the cup to prevent the backward rotation of theresilient member, and a means on the resilient member for engagementwith means on the cup to prevent longitudinal movement of the resilientmember on the cup.

2. In an oil'feeding device, a combination with an oil cup having anannular groove, ratchet teeth arranged adjacent the groove, and a screwplug for engagement in the cup having a longitudinal groove formedtherein, of a spring ring engaged over said ratchet teeth, :1 lug on thering for engagement in the groove of the plug, a head on the ring forengagement in the groove of the cup, and a shoulder on said ring forengagement With said ratchet teeth, whereby said ring is preventedmoving backwardly in the cup, or longitudinally therefrom.

In testimony whereof We afiix our signatures, in presence of twoWitnesses.
